Air passengers are facing travel chaos as Aer Lingus workers plan to strike on June 16th and June 18th.

Impact have tonight issued airline bosses with notice of two further one-day strikes -just one week after a 24 hour strike left 30,000 passengers grounded and cost the airline €10 million.

A two day strike will cost Aer Lingus more than €20 million and could see over 60,000 passengers stranded in the middle of the holiday season.

The bombshell came after talks to solve the deadlock over the new roster arrangements for cabin crew broke down this evening

The union said management had refused to negotiate in good faith and instead issued a take-it-or-leave-it proposal.

Impact said the deal offered would be unacceptable to staff because it would mean hundreds of jobs losses in Aer Lingus and Irish companies that rely on its business.

IMPACT official Michael Landers said the union had been willing to continue talks over the weekend, but management walked away.

Mr Landers said management’s only proposals in three days of talks would require staff who currently fly short and long haul flights to be rostered solely for one or the other.

This would immediately make the crewing of transatlantic flights from Ireland unviable because it would be impossible for cabin crew to meet their targets for flying hours (called ‘block hours’) if they only flew transatlantic flights.

Block hours do not take account of the time staff are on duty when they are not actually flying.

He said: “By tabling a clearly-unacceptable take-it-or-leave-it proposal, which would inevitably lead to hundreds of Irish jobs being exported to the USA, management has demonstrated that it never intended to negotiate in good faith – and that it cares little about unemployment or the Irish economy.

"Management negotiators have blankly refused to test a ‘5:3’ roster across long and short-haul flights, even though pilots deliver an effective and profitable service by working similar rosters."

Aer Lingus has threatened to move the 300 cabin crew jobs to the US if it can't get a deal with staff in Ireland.

Unions claim Current rosters mean they can work up to 60 hours in a seven-day period, resulting in shift patterns of six working days and one rest day, followed by six more working days.

It has branded the crew roster patterns are "erratic, unpredictable and subject to changes at very short notice."

Mr Landers said: “Many cabin crew are struggling to maintain caring arrangements when they are on duty and many have reported incidences of extreme fatigue necessitating medical attention. It cannot continue like this.
